Description

[Detailed description of the invention]

[Purpose of gQ Light] (Industrial Application Field) The present invention relates to a coke transport device for transporting purified coke to a coke dry extinguishing system in a coke refinery. (Prior art) - At the cous refining plant T, charged coal is carbonized to refine coke as fuel for blast furnaces. It has a sensible heat content of approximately 1.47 million KJ per ton. Therefore, since the temperature is too high at 15 to send the coke as it is (to a 41st culm blast furnace and use it), the coke manufactured by VJ is first put into a coke dry extinguishing system (hereinafter referred to as CDQ) and the coke retains its contents. Sensible heat is recovered. A fire extinguishing train and a crane are used to transport the coke from the coke oven to the CD Q. Figure 3 shows a conventional coke transport system of this type. This shows an example, in which coke is taken out from the oven 2 inside the coke oven 1 and loaded onto a packet 3. This packet 3 is placed on the fire extinguishing train 4-1, and when the fire extinguishing train 4 is driven. The operation of the motor 4M is controlled by a transporter control device 5. When the coke is loaded into the bucket 3, the carrier 4 is moved so that the packet 3 is located at the bottom of the crane 7. Then, the drive motor 7M of the crane 7 rotates, and the buckets 1 to 3 loaded with trash are lifted up.
It is transported to the -F section of CDQ8. In this situation r♂, the operator judges whether or not there is enough room to throw coke into the CDQ8, and if there is room, the coke loaded in packet 3 is thrown into the CDQ8. If packet 3 is CDQ8
Avoid waiting at the top of the 0DQ8, and add coke after there is enough room to put it inside the 0DQ8. However, in such a device for transporting food, the food can be kept in the packet 3 for tens of minutes or more due to the high temperature, and the packet 3 may be deformed by the heat. Resulting in. Also, the high temperature coke is 1! at the top of CDQ8! Ji
Doing so is extremely dangerous and emits radiant heat, making it difficult for operators to approach the surrounding area. (Problem to be solved by the invention) As described above, in the conventional coke conveying device,
]-After the coke is loaded into the packet 3 and transported to the top of the CDQ8, it is determined whether or not the coke can be introduced into the CDQ8. Therefore, if coke cannot be added directly, the high-temperature coke may remain in one part of the CDQ8 for several tens of minutes, causing deformation of the packet σ and the heat generated from the coke. Therefore, there was a problem that the operator could not get close to the surrounding area. In order to solve such conventional problems, this invention
Its purpose is to transport coke to be put into a coke extinguishing system.
To provide a transportation control device in which a coke transportation container loaded with coke is not kept waiting during transportation. [Structure 1 of the Invention (Means for Solving the Problems) - In order to achieve the object described in F, the present invention provides a system for sequentially taking out coke refined in a coke oven having a coke oven having a dispersion kiln and placing it in a transport container. In the equipment in which coke is loaded and transported by a transporter to a coke extinguishing device and coke is immersed in the coke extinguishing device, the amount of coke accumulated in the coke d4 extinguishing device is monitored and new coke is introduced. storage V4F1 determination means for determining whether there is enough room for the amount of coke, and only when it is determined by the storage value determination means that there is enough room for putting coke into the coke extinguishing system, The present invention is characterized by comprising: a transporter control means for giving a driving command; (Function) In the coke transport control device according to the present invention, there is enough room to newly introduce coke into the coke extinguishing device by the accumulation amount determination means attached to the coke extinguishing device. It is determined whether or not. (
Then the coke was given to an official (J Ruda).

Only when it is determined that there is a margin for [ ], the transporter control means issues an operation command to the transporter. Therefore, at the same time as the transporter 4 transports coke, coke can be introduced into the coke extinguishing system. (Embodiment) FIG. 1 is a block diagram C showing an embodiment of the present invention. As shown in the figure, coke ovens 1 (1a, Ib) are provided at two locations, and the inside of each coke oven 1 is divided into a plurality of Pi ovens 2 (2a, 2b). In the 8th kiln 2, coal is burned and carbonized to refine coke. The coke refined in the eight ovens 2a and 2b is loaded into a first packet 3a and a second bucket 3b, respectively.
The first fire-fighting train 4a and the second fire-fighting train 4b alternately transport the fire-fighting train to the lower part of the crane 7. The packet 3 is then lifted by the crane 7 and transported to the top of the coke dry extinguishing system 8 (hereinafter abbreviated as CDQ). Also, when loading coke into the packet 3, the coke taken out does not scatter. CDQ8 is a container that accumulates coke, and uses inert gas circulating inside to extinguish and cool the coke and recover sensible heat. A level sensor 9 is installed to detect the amount of accumulated coke.The level sensor 9 determines whether there is enough room to newly introduce coke into the CDQ8.
If there is enough room for loading, the contact is turned on, and if there is not enough, the contact is turned off.This output signal is then supplied to the transport machine control device 5. The machine control device 5 takes in the output signal of the level sensor 9, and also controls the operation of each fire extinguishing train 4a and 4b.

Next, according to the flowchart shown in FIG. When started, each fire extinguishing train controller 12a, 12b controls the drive motor/IMa, 4Mb of each fire extinguishing train 4a, 4b to each fire extinguishing main vehicle 4a (4b is located at position 4 in front of the kilns 2a, 2b). Activate it (step 5TI). And, so that the transportation of coke starts from the first fire-fighting train 48, what about the fire-fighting train? The fr number n is set to "n=1" (step 5T2). After that, the output signal of the level sensor 9 determines the CDQB.
It is determined whether or not there is enough room to add new coke (step ST3'). Here, there is room to put coke into CDQB (
If FIfi is determined (YES in step ST3), the kiln 2
Coke is taken out from a and loaded onto the first packet 3a placed on the first fire extinguishing train 48 (step 5T4). Thereafter, the first fire extinguishing train 48 is moved to the lower part of the crane 7 (step 5T5), and the first packet 3a loaded with coke is lifted by the crane 7, and the CDQB
(Step 5T6). Here, the output signal 3 of the level sensor 9 causes the CD
It is determined whether there is enough room to put coke into QB (step 5T7), and if it is determined that there is room (YES in step ST7),

a, and move this first fire extinguishing train to a position ψ in front of the kiln 2a (step 5r9). After that, if it is determined whether or not to finish the transportation work at step 5TIO, and the transportation work is ended (
If the answer is YES in step J3110, the execution process in J3 in the script processing unit 11 ends. On the other hand, if you want to continue the transportation work (N in step 5110)
In o), the second fire extinguishing train 4b is selected this time (Stella 7 ST12>, and the process returns to step ST3, and the following operations are repeated. 'l fire electric train 4a is selected (step 5T13), and the coke is transported in the intersecting direction between the first fire electric train 48 and the second fire electric train 4b.In this way, in this embodiment, After confirming based on the detection signal from the level sensor 9 that there is enough room to put coke into the CDQB, the packet 3 is loaded with coke and transport is started. Packet 3 loaded with coke is not held in the middle of Luck! 2, and coke can be introduced at the same time as it is transported to the top of CDQ8. Therefore, the packet is said to be deformed by the heat of coke. In addition, the drawback that the operator cannot get close to the surrounding area due to the heat radiated from the coke is eliminated, improving safety.Furthermore, all coke transportation is automatically operated. , manual operation by the operator is eliminated, work efficiency is improved, and the occurrence of operational errors can be prevented. [Effects of the Invention] As explained above, in the present invention, After confirming that there is enough space to newly introduce coke into the coke extinguishing system using the stored amount judgment means, the operator controls transporter #2 to start transporting coke. Therefore, the transport container loaded with high-temperature coke is no longer kept waiting during transportation, and the transport container is no longer deformed due to the heat of the coke. Due to the radiant heat generated from the ``axes'', the drawback that the operator is not able to move closer to the operator is eliminated, and the effect of increasing the safety f1 in the ``axes conveying process'' is obtained.
